Abstract: The present invention is a method of stabilizing hydrogen peroxide in an aqueous solution, such as a circulating water slurry, comprising a peroxide, such as hydrogen peroxide. The aqueous solution may include organic matter. The method comprises adding an aldehyde donor, such as a methylolhydantoin, to the solution (or slurry). The inventors have discovered that aldehyde donors significantly reduce the decomposition of hydrogen peroxide by catalase and other peroxide decomposing enzymes, which are often present in recycled paper. As a result, less hydrogen peroxide needs to be added to a solution to effectively bleach organic matter in the solution. Furthermore, aldehyde donors are safe to handle and cost effective. Another embodiment is a method of bleaching recycled papers in a circulating water slurry comprising organic matter. The method comprises adding hydrogen peroxide and an aldehyde donor to the slurry.

Abstract: The present invention relates to a starch compositions that include biodegradation inhibitors which are low free formaldehyde formulation of one or more formaldehyde donor compounds. The starch compositions may also contain an additional inhibitor comprising one or more isothiazolone compounds which, when combined with the formaldehyde donor compounds, results in a synergistic blend. Methods for inhibiting starch biodegradation are also disclosed.

Abstract: Disclosed are stable, liquid broad spectrum preservative formulations comprising (a) an antimicrobial halopropynyl compound and (b) a butoxydiglycol solvent, and optionally (c) (i) an alkanol substituted dialkylhdantoin formaldehyde donor, (ii) an antimicrobial isothiazolone derivative, and (iii) a stabilizer. The invention is also directed to methods of use of the preservative formulations for inhibiting or retarding the growth of bacteria or fungi.
